Short version - these are actually very quiet for a 5015 blower, but don't move a ton of air compared to some others either. I'm keeping them on my 3D printer though. I can live with the lower airflow in exchange for very quiet operation.I was using WINSINN "quiet" 24 volt 5015 fans on my 3D printer before, but the noise was so loud it drove me nuts and I almost always printed with my fans off because of it. I could hear them across the house. I just ordered these fans along with some Quiet worth itI absolutely have no idea, why the first one lost its hair. Sorry I meant one fan blade. I have no recollection that I mistreated the device. Yet, when I looked at it the other day, there was a fan blade missing. Mysteriously, I could not find the missing piece and I haven't swept the floor for a while.Well, I installed another one that seems to fine.Ahh, almost forgot: It is another mystery to me, why they don't add more hookup wire to the fan. I mean, cutting it shorter is easier than extending or replacing the stock wire with a longer one. The stock length is a little longer than a Cuban cigar. Unless you install the fan into a micro enclosure, the wire will always be too short.Has a high pitched whineThese just weren't usable with what we needed them for.These work well for 3D printing! They move enough air for my Ender 3 Pro, and are decently quiet. If you need to move A TON of air, may not be the best but work well for normal applications.El material se ve de buena calidad, hasta ahorita funcionando sin problemasReplaced the part cooling fan on 2 of my 3D printers with these, and they reduced the noise significantly.So I thought the fan died on my essential oil diffuser so I got these. Turns out the fan was fine but the circuit board wasn’t delivering the necessary amperage to run these or the OEM fan.These are a little more powerful. Bypassed the circuit board on the essential oil diffuser and now it blows aromatherapeutic mist like a hawt-dang.It’s a little louder too.I like it.
